In good faith, the Dutch Rugby Association hopes that nothing bad would happen from letting transgenders play. Because of course that is not what you intend to let happen as the Dutch Rugby Association told me.  

In a contact sport like rugby, safety and fair play is the bedrock, when I was a younger girl I never played against the older boys, neither did I play against the younger Dutch girls coming through the ranks, it’s an unfair advantage. Even men don’t just play at the top championship level without a lot of training, it’s far too dangerous. Unfortunately I was to learn from the Dutch Rugby Association that safety has been relegated. I am a guinea pig.

When the Dutch Rugby Association went against the World Rugby Guidelines in 2020, they came out with a press release, putting inclusion on top:

“We see rugby as an inclusief sport and believe that rugby is for everyone. It is a contact sport, with a large social aspect. The interpersonal contact is central, the respect for each other is what defines the sport. Only looking at (possible) physical differences means that transwomen are in advance ruled out. We find this undesirable and don’t support this. “

This extract from the press release shows their reasoning why they choose to accept biological men in my sport. They have not written anything down in their rulebooks or anywhere else about safety with transgenders. Nothing, nothing about male puberty, hormone blockers, monitoring compliance or medical reassignment. 

Rugby Association Site transgender search shows that there is no information to be found.

There seems to be no active policy to make rugby safe for its players. It is unbelievable with all the overwhelming scientific research the Association just hoped that nothing would happen. We are being used as guinea pigs to see what happens.

‘Dutch women’s rugby will become meaningless without fair competition’

Dutch rugby has become meaningless without fair competition. The concept of fair play, the bedrock of all competitive sport, has been undermined by the Dutch Rugby Association statement. It is a long-established principle that fair and meaningful competition is achieved by grouping different body types into different categories. This is why we commonly see competition based on differences in age, weight and other factors. This is also why sport is divided into male and female sex categories.
